CAR-TRUCK.

SPECIFICATION forming*n part Of Letters Patent N0. 599,882, dated March. 1, 1898.

Application filed November 13J 1897. Serial No. 658,388. (No model.) l

To a/ZZ whom it may concern.-

Beit known that I, BENJAMIN W. TUCKER, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Car-Trucks, of which the following is a speciiication.

The invention relates to improvements in car-trucks, and pertains particularly to the side frames of the truck, the transom `connecting the side frames, and the pedestals at the ends of the side frames to receive the axleboxes and admit of thelatter having a verti- .cal reciprocating movement, as hereinafter describedl and claimed.

In the embodiment of the invention illustrated in t-he accompanying drawings the side frames and transom are shown as'having been made of pressed steel and the pedestal-frame sections as having been formed of cast metal. The side frames have upper and lower inwardly-extending horizontal flanges and verfical end flanges which close the ends of the side frames and connect the said upper and lower iianges. Within the web portions of the side frames are vertical pedestal-spaces, and to these spaces are applied pedestalframes of special character, both of said pedestal-frames being preferably of cast metal. The pedestal-frames furnish the rubbing-surfaces for the axle-boxes, so that no wear from the action of the boxes comes uponthe side frames of the truck.

The axles-boxes used in'this truck are of the usual character, and above them will be arranged suitable springs, Whose upper ends will be housed in suitable sockets formed, as hereinafter described, to receive them.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in whichl,

Figure 1 is an end view, partly broken away, of a car-truck constructed in accordance with and embodying the invention. Fig. 2 is a side elevation of same. Fig. Slis a top view, partly broken away, of same. Fig. 4 is a vertical section of same on the dotted line 4 4 of Fig. 3. Fig. 5 is a detached perspective view of one of the pedestal-frame sections. Fig.'6 is a like view of the lower pedestal-frame section, and Fig. 7 is a like view of a portion of the side frame of the truck.

In the drawings,A designates the side frame or beam of the car-truck, and B the transom connecting, the side frames, which are duplicates of one another4 and only one of which is therefore illustrated. Y v

The side frames or beamsA are formed by preference of pressedV steel, and each side frame A is formed with the upper inwardlyextending horizontal flange C, the lower inwardly-extending flange D, and the end vertical flanges E, the latter, as clearly illustrated in Fig. 7, connecting and being integral with the upper and` lower flanges C D and forming a box-like section at each end of each side frame A. The form of the upper and lower flanges C D is more clearly illustrated in Fig. 3, in which the outline of the lower flange D is indicated by dotted lines'.

Adjacent to the ends of each side frameA is 'formed the pedestal-spaces F F to receive the axle-boxes, springs, and pedestal-frames. The pedestal-spaces F extend upward into the web of the side frame A, but do not reach the upper flanges C of said side frame, and said pedestal-spaces F break thev continuity of the lowe'r flange D of said frame, but leave a portion of said flange at the outer side of each pedestal-space. Above. the pedestalspaces F the side frames A extend outward, as clearly illustrated in Figs'. 4 and 7, to form a portion of the socket for the usual coiled springs, which in use are located over the axle boxes, and this outwardly -extending portion of said frames A is lettered G. The upper flange C of the side frame and the outwardlyextending portions G of said side frame are integral with one another.

At the inner side of each end of the side frame A is applied an inner section or pedestal-frame section H, which will preferably be of cast metal and in one integral piece, as illustrated in Fig. 5. The inner pedestal- IOO per flange C of the side frame, and the vertical portion M, connecting the flanges J J at their upper ends and with the forwardly-projecting portions G of the side frames forming substantially circular sockets or receptacles for the usual springs, which in use areloeated over the axle-boxes. The upper flange L of the inner pedestal-frame section His formed with the outwardlyextending portion N, which, as illustrated in Fig. 4, extends outward below the top of the outwardly-projecting portions G of the side frame A. The vertical portions M of the pedestal-frame sections H proj ectin ward in a direction from the side frame A, and that portion of the same which is inward beyond the line of the upper flange C of said frame extends upward above the flange L a distance equal to the thickness of the said flange C, as illustrated in Fig. 4, in order that the upper surface of said portion M and the upper surface of the said flange C may be on the same horizon tal plane, whereby the side frame A from end to end is enabled to have a horizontal upper surface. The inner pedestal-frame sections II are secured to the side frames A by means of rivets passing through the said side frames and the flanges I L of said pedestal-frames, and said pedestal-frames II are further secured to the side frame A by means of the bolts O, passing vertically through the flanges K of said pedestal-frame sections, the lower flange D of the side frame, and the flanges of the lower pedestal-frame section P, as illustrated in Fig. 2. The inner pedestal-frame sections H are further strengthened in their connection with the side frame A from the fact that the outwardly-proj ect-in g portion N of said pedestalframes enter the socket portions G of the side frames and that the upper portions of the socket-sections M of the said inner pedestalframe sections H contact with the inner vertical edges of t-he upper flange C of said side frame.

The lower pedestal-frame sections P are each preferably east in one integral piece, and each is formed with the vertical transverse flanges Q, which form the rubbing-surfaces for the axle-boxes, longitudinal flanges R, which lit against the outer face of the side frame A, the lower horizontal flange S,whieh connects the lower ends of the vertical flanges Q and closes the lower ends of the pedestalspaces, and the horizontal flanges T, which it against the lower surfaces of the lower flange D of said frame and are apertured to receive bolts O, which pass through said flanges T, the lower flange D of the side frame, and the lower horizontal flanges K of the inner pedestal-frame sections H. The lower pedestalfrarne section P is substantially of U shape, and its vertical transverse flanges Q, extend inward along the sides of the pedestal-spaces F and along the facing surfaces of the lower portions of the flanges J of the inner pedestalframe section II, and said flanges Q of the lower pedestal-frame sections P furnish the rubbing-surfaces for the axle-boxes. The longitudinal flange R of the lower pedestalframe sections P follows the general outline of the vertical flanges Q and horizontal flanges S Tof said lower pedestal-frame sections, and thus in every part the said lower pedestalframe section is of an gie-iron shape in section.

The transom-beam B, which connects the side frames or beams A, will be of pressed steel and in one integral piece of the outline shown-that is to say, having the vertical sides a a, the horizontal flanges b l) at the upper edges of said sides c and extending from one another, and the bottom d, which connects the sides d c, and with said sides forms in cross-section a U shape. The bottom dof the transom-beam B is preferably formed with openings e to permit of the escape of rain or dust which may accumulate between the sides de, and the middle portion of the sides a a and bottom d of the transom-beam Bis of greater depth than the ends of said beam, as illustrated. The ends of the transom-beam B extend outward between the upper and lower flanges C D of the side frames A, and the ends of said transom-beam B are secured to said flanges C D in the manner illustrated in Figs. 2 and 3, in which it will be seen that the upper flanges b of the transom-beam B are riveted to the upper flange C of the side frame A and that the bottom d of the transom-beam B is at its end riveted to the lower flange D of the side frame A.

The side frame A will preferably be in one integral piece of pressed steel. The transombeam B will also preferably bein one integral piece of pressed steel. The inner section Il applied to each end of the side frame A will preferably be in one integral piece of east metal, and the lower pedestal-frame P will preferably be in one integral piece of east metal, although I do not limit the invention to casting the lower pedestal-frame section P in one pieec,sinee^it is evident that the flanges Q, R, and S-of-said section may be in one piece of pressed steel and the flanges T in separate pieces of pressed steel riveted to the other portions of the said pedestal-frame section P. Y

For convenience the inner sections II are termed herein pedestal-frame sections, but it will be apparent from an inspection of the drawings that the frames P are the pedestals proper, since they receive and furnish the rubbing andguiding surfaces for the axleboxes. The pedestals P are removable at will.

That I claim as my invention, and desire to secure by Letters Patent, is-` l. In a ear-truck, the side frames or beams having the upper and lower inwardly-extending flanges, vertical pedestal-spaces and outwardly-projecting socket-sections above said spaces and integral with said side frames and closed at their upper ends by the upper horizontal portions of said side frames, combined with pedestals applied to said spaces, and the inner sections having the inwardly-projecting lOO IIO
